How GIS Has Changed Our World

The tornado outbreak that killed at least 327 people in the Southeast last week may have been the largest in U.S. history, with an estimated 305 twisters, according to the National Oceanic and Atmospheric Administration. The storms have destroyed or damaged power plants, power lines, gas stations, and water supplies, leaving more than 1 million people without electricity. Thousands are homeless or without fuel or safe drinking water. Three nuclear power plants have shut down and are offline.
